Optimal Connector Shells Ensure More Stable and Reliable Solutions

Finned top and flat top connector shells are different in size and application solutions, delivering deep insights for your business.

800G OSFP optical modules integrated in a heat sink are applicable for Spectrum-4 Ethernet switches. Its top heat sink provides the necessary thermal management when processing massive data.

Flat Top module's height is 9.5 mm without heat sinks, relying on the heatsinks on the NIC ports to assist the module in cooling. 400G OSFP form factor optical modules are used in CX7 NICs.

Questions & Answers

Ask a Question

Can a 400G OSFP DR4 be interconnected with an 800G 2xDR4?

Yes, it is possible. The 800G dual-port 2xDR4 can be connected to two 400G DR4 optical modules using two single-mode MPO-12/APC jumpers.

Can QSFP-DD 400G DR4 be interconnected with OSFP 400G DR4?

Even though QSFP-DD and OSFP have different standards, QDD-400G-DR4 and OSFP-400G-DR4 are still interconnected and they have the same standards on the optical side; this is one way to interconnect NVIDIA CX7 OSFP-packaged 400G NICs with 400G QSFPDD switches.

Can QSFP-DD ports use modules in OSFP form factor, such as OSFP-400G-DR4?

OSFP and QSFP-DD are two completely different form factors, so OSFP optical modules cannot be used in OSFP ports.
